Just take into consideration that wherever Mark goes, so goes his extended family and all the craziness THAT entails!
Why do you think he's looking for:
4 bedrooms (that's more than we had in the house growing up with 8 kids - hopefully he'll have more than one bathroom!);
lots of elbow room (that's so the neighbors can't see when the family arrives and can't hear when we start "discussing" stuff);
2+ car garage (that's sleeping accomodations for me and the 3 cats);
near water (that's to drown those of us who get out of control);
woods (he loves going on family hikes - hoping maybe he'll come back with fewer than he left with!)
The guy is not dumb!
